RAIL CLAMP.

Application filed December 23, 1922. Serial No. 608,753.

1 0 all whom it may concern Be it known that I, RICHARD EARL NEELY, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented new and useful Improvements in Rail Clamps, of which the following is a specification.

This invention relates to improvements in clamps especially'ada-pted for securing trolley wire insulators to the supporting beams in mines, an object being to provide a clamp which may be quickly and easily applied to an ordinary overhead railroad rail or I- beam, (as commonly used in mine tunnels) whereby an insulator may beattached for the support of a trolley wire.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure l is a transverse section through a rail with the invention attachedl Figure 2 is a fragmentary view at right angles to Figure 1.

Figure 3 is adetail perspective view of one member of the clamp.

Figure 4: is a similar view of the other member.

Referring in detail to the drawings, wherein like characters of reference denote corresponding parts, the clap is shown as com-v prising a pair or" relatively adjustable members 10 and 11, each of which includes a head 12, while extending from this head are upwardly and inwardly inclined lips 13. The heads 12 together withthe lips 13 provide'notches Ll for the reception of the flanges of the rail or I-beam, the former being illustrated. and indicated at 15. The lips are adapted to overlie the opposite side edges of the flange 16 of the rail, so that when the members 10 and 11' are secured together in a manner to be hereinafter eX- plained, the lips 13 will tightly grip the flange of the rail.

Extending inwardly from each of the heads 13 is a bar 17, the bar otthejmember 11 bemg offset with-respectto the bar of the member 12 and providing a space for the reception of the last mentioned bar-J Extending downwardly from the inner end of the.

bard? of the member 11 is a lug 18, while a similar lug-19 extends down fromiand forms a part of the head 12 of the member 10.1

The lugs 18 and 19 are provided with openings and the opening in the former lug is I threaded for engagement with the inner end ot an adjusting bolt 20, whose head bears against the outeri'ace of the lug 19.

l lxtending downwardly from the member i1. is a threaded lug 21, withwhich asuitable insulator'is adapted to threadedly en:- gage, so that when the clamp is secured to the support which is herein shown as the rail 15, the insulator will serve as a support fora trolley wire. r

It is preferred to provide insulation 22 and 23 between the rail l 5 and the members 1Q and'll of the clamp, so that if desired, a w1re engaging member other than an insulator-may be attached to the lug 21.

The invention is susceptible of variousv changes in its form, proportions and minor details of construction and the right is here-L in reserved to. make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is: r

A clamp of the class described compris-- i ing a pair of'relatively movable members each of said members including a head, a

lip extending from said head, a bar also extending from said head. the bars 01"? one head being ofi'set with respect to the bars of the otherheads, with the bars arranged in overlapping lGldtlOlL, means carried by' one 7 of saldmembers for attachment, to an insu-' later, a lug carried by each member and provided with an opening and a bolt extendlng from the opemngs held in adjusted position. In testimony whereof I whereby the members may be relatively adjusted and aflix my signature.
